LAMP REFLECTOR Filed Jan. 21, 1932 EH 5#1s077 Patented July 11, 1933 UN'lTED STATES PATENT 'FFIQE EDWARD H. MATTISON, OF MABSHFIELD, WISCONSIN LAMP REFLECTOR Application filed January 21, 1932'. Serial No. 587,883.

This invention appertains to illumination, and more particularly to a novel reflector-and guard for incandescent lamps.

One of the primary object of my invention is to provide a novel reflector and guard for an ordinary lamp socket, whereby the lamp and socket will be particularly adapted for vuse as a trouble light, the device, however, being susceptible for other uses and purposes.

A further salient object of the invention is the provision of a reflector formed from a single sheet of metal or other suitable mate- I, rial, suitably folded to provide a flared reflector or body and sleeve for engaging the socket, with'means for holding the adjacent edges of the reflector in position against displacement. a, v

A further object of my invention is the 0 provision of diametrically disposed laterally I guard itself, whereby a cheap and durable structure will be had, and whereby the same can be readily associated with the lips of the reflector.

A further object of my invention is the provision of a novel supporting bracket for permitting the suspension of light from an overhead support, the bracket also forming means for retaining the socket engaging portion of the reflector about the socket.

A still further object of my invention is to provide an improved device of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 is a fragmentary front elevation of my-inl'proved device, with parts thereof broken away and in section; I

Figure 2 is a side elevation of my improved device, showing parts thereof broken away and. in section;

Figure 3 is a detail section taken on-"the line of Figure 2 looking in the direction of the arrows and illustrating more particularly the supporting bracket for permitting I the device to be detachably connected with an overhead-support.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several 65:

views,'the letter A generally indicates my improved device for an electric light socket B carrymg an incandescent or like lamp C.

"The electric light socket B and the lamp C are of the ordinary or any preferred character and the feed wires 5 for the lamp extend into and are connected with the socket in the ordinaryway.

My improved device A comprises the novel reflector 10 and guard 20,*which are assoelated together 111 a novel manner, as will be later described. a

The reflector 10 can be formed of sheet met-j. al or anyother desired material, and is preferably formedv from a single blank of sheet 501 material.

The blank is folded to provide the flared reflector portion 11 and the narrow neck or sleeve portion 12 for engaging the body of the light socket B. The edges of the blank L;

of the sheet material are arranged in overlapping relation as indicated by the reference character 13 and can be secured together in any desired way, such as by the use of a 9 rivet 14.

Formed on the outer side edges of the reflector are the laterally extending lips 15. The lips 15 are disposed diametrically opposite one another and on opposite sides of the W; overlapping edges 13 of the reflector. The

lower ends of the lips 15 are folded back upon themselves to provide hinge barrels 16, and suitable fastening screws 17 can be passed through the folded portion of the lip and the body portion of the lip and retained in position by means of the nuts 18. The use of the hinge barrels 16 will be hereinafter more fully set forth.

Referring more particularly to the novel guard 20, it is to be noted that the same includes a pair of like companion members 21 and 22. Each of the companion guard members 21 and 22 is formed from a single length of wire and each length of wire is folded to provide the angularly extending arms 23. As shown, each of theguard members forms a substantial triangular structure and the arms of one member is arranged between the arms of the other member and interlaced therewith, as clearly shown in Figure 1 of the drawing. The ends of the wire from which each of the guard members is formed, are twisted together and then spread apart to provide jaws 24. These jaws 24-are arranged on opposite sides of theguard and receive the screws 17 and are held in place thereby.

In order to provide a support for the reflector, a supporting bracket or the like 25 can be provided. This bracket 25 may include arms 26 having the inwardly directed legs 27, which are received within the hinge barrels 16. I

Means can also be provided for associating the reflector and guard with an overhead support and this means consists of a hanging bracket 30. The hanging bracket 30 is also formed fromv a single length of wire and is doubled intermediate its length back upon itself, and the adjacent portions are twisted together, as at .31, intermediate their ends. The upper end of the bracket is curved to provide a hook 32 for engaging an overhead supporting structure.

The strands forming a part of the hanging bracket below the twisted portion 31 are spread apart to form arcuate clamping arms 33. The lower ends of the clamping arms 33 are then further folded to form eyes 34, which receive a holding bolt 35. The clamping arms 33 are placed about the narrow neck or sleeve portion 12 of the reflector and are clamped thereon by the bolt 35, heretofore referred to. Thus, the bolt and the clamping arms form not only means for connecting the hanging bracket with the reflector, but also as means for holding the split sleeve or narrow neck portion of the reflector on the lamp socket B.

From the foregoing description, it can be seen that I have provided an exceptionally simple and novel form of reflector and guard for an ordinary incandescent lamp and socket.

Changes in details may be made without departing from the spirit or the scope of this invention. 7

I claim:

1. In a device of the class described, a

reflector having laterally extending lips on its opposite sides, a guard for the front of the reflector lncluding a pair of companion members each formed from a slngle wire length including a plurality of angularly extending arms, the arms of one member being arranged between the arms of the other memher, the ends of the wires of each member being twisted together and provided with eyes and fastening elements extending through the eyes and lips.

2. In a device of the class described, a reflector having laterally extending lips formed on the opposite sides thereof, extensions formed on the lips folded back against the body portion ofthe lips t-OPI'OVIlClG hinge barrels, fastening elements extending through the extensions and body portions of the lips, a guard for the reflector having means formed on the. opposite sides thereof for engaging said fastening elements and a supporting bracket having inwardly directed legs received in said hinge barrels.

In testimony that I claim the foregoing I have hereunto set my hand at'Marshfield, in the county of \Vood and State of Wisconsin.
